[enstorm]At least as far as the pistol cartidges go, I am not convinced they offer a serious advantage over the taper crimp you get with a standard seater die[/quote]

I also use the LEE FCD for 9mm. It doesn't use a collet to apply a taper crimp, just a "slug" that is pressed over the bullet and the mouth of the case to apply the crimp. What I like about the Pistol FCD is that it sizes the full length of the case after the bullet is seated. It "irons out" any bulge that may occur when the bullet is seated and insures that the round will chamber properly. No more need for a case gauge and no more FTF's.
